&lt;script language=&quot;javascript&quot; type=&quot;text/javascript&quot; src=&quot;jquery.min.js&quot;&gt;&lt;/script&gt;
&lt;script language=&quot;javascript&quot; type=&quot;text/javascript&quot; src=&quot;jquery.jqplot.min.js&quot;&gt;&lt;/script&gt;
&lt;link rel=&quot;stylesheet&quot; type=&quot;text/css&quot; href=&quot;jquery.jqplot.css&quot; /&gt;</pre></blockquote><h4 class=CHeading>Add a plot container</h4><p>Add a container (target) to your web page where you want your plot to show up.&nbsp; Be sure to give your target a width and a height:</p><blockquote><pre>&lt;div id=&quot;chartdiv&quot; style=&quot;height:400px;width:300px; &quot;&gt;&lt;/div&gt;</pre></blockquote><h4 class=CHeading>Create a plot</h4><p>Then, create the actual plot by calling the $.jqplot plugin with the id of your target and some data:</p><blockquote><pre>$.jqplot('chartdiv',  [[[1, 2],[3,5.12],[5,13.1],[7,33.6],[9,85.9],[11,219.9]]]);</pre></blockquote><p>Which will produce a chart like:</p><img src="images/basicline.png" width="416" height="317"><h4 class=CHeading>Plot Options</h4><p>You can customize the plot by passing options to the $.jqplot function.&nbsp;  Options are described in <a href="jqPlotOptions-txt.html#jqPlot_Options" class=LSection id=link1 onMouseOver="ShowTip(event, 'tt1', 'link1')" onMouseOut="HideTip('tt1')">jqPlot Options</a> in the jqPlotOptions.txt file.&nbsp;  An example of options usage:</p><blockquote><pre>$.jqplot('chartdiv',  [[[1, 2],[3,5.12],[5,13.1],[7,33.6],[9,85.9],[11,219.9]]],
{ title:'Exponential Line',
  axes:{yaxis:{min:-10, max:240}},
  series:[{color:'#5FAB78'}]
});</pre></blockquote><p>Which will produce a plot like:</p><img src="images/basicoptions.png" width="417" height="315"><h4 class=CHeading>Using Plugins</h4><p>You can use jqPlot plugins (that is, plugins to the jqPlot plugin) by including them in your html after you include the jqPlot plugin.&nbsp;  Here is how to include the log axis plugin:</p><blockquote><pre>&lt;link rel=&quot;stylesheet&quot; type=&quot;text/css&quot; href=&quot;jquery.jqplot.css&quot; /&gt;
&lt;!--[if IE]&gt;&lt;script language=&quot;javascript&quot; type=&quot;text/javascript&quot; src=&quot;excanvas.js&quot;&gt;&lt;/script&gt;&lt;![endif]--&gt;
&lt;script language=&quot;javascript&quot; type=&quot;text/javascript&quot; src=&quot;jquery.min.js&quot;&gt;&lt;/script&gt;
&lt;script language=&quot;javascript&quot; type=&quot;text/javascript&quot; src=&quot;jquery.jqplot.min.js&quot;&gt;&lt;/script&gt;
&lt;script language=&quot;javascript&quot; type=&quot;text/javascript&quot; src=&quot;jqplot.logAxisRenderer.js&quot;&gt;&lt;/script&gt;</pre></blockquote><p>Important note:  For jqplot builds r529 and above (0.9.7r529 and higher), you must explicitly enable plugins via either the { show: true } plugin option to the plot or by using the $.jqplot.config.enablePlugins = true; config options set on the page before plot creation.&nbsp; Only plugins that can be immediately active upon loading are affected.&nbsp;  This includes non-renderer plugins like cursor, dragable, highlighter, and trendline.</p><p>Here is a the same $.jqplot call but with a log y axis:</p><blockquote><pre>$.jqplot('chartdiv',  [[[1, 2],[3,5.12],[5,13.1],[7,33.6],[9,85.9],[11,219.9]]],
{ title:'Exponential Line',
  axes:{yaxis:{renderer: $.jqplot.LogAxisRenderer}},
  series:[{color:'#5FAB78'}]
});</pre></blockquote><p>Which produces a plot like:</p><img src="images/basiclogaxis.png" width="416" height="312"><p>You can further customize with options specific to the log axis plugin:</p><blockquote><pre>$.jqplot('chartdiv',  [[[1, 2],[3,5.12],[5,13.1],[7,33.6],[9,85.9],[11,219.9]]],
{ title:'Exponential Line',
  axes:{yaxis:{renderer: $.jqplot.LogAxisRenderer, tickDistribution:'power'}},
  series:[{color:'#5FAB78'}]
});</pre></blockquote><p>Which makes a plot like:</p><img src="images/basiclogoptions.png" width="416" height="310"><p>For a full list of options, see <a href="jqPlotOptions-txt.html#jqPlot_Options" class=LSection id=link2 onMouseOver="ShowTip(event, 'tt1', 'link2')" onMouseOut="HideTip('tt1')">jqPlot Options</a> in the jqPlotOptions.txt file.</p><p>You can add as many plugins as you wish.&nbsp;  Order is generally not important.&nbsp; Some plugins, like the highlighter plugin which highlights data points near the mouse,  don&rsquo;t need any extra options or setup to function.&nbsp;  Highlighter does have additional options which the user can set.</p><p>Other plugins, the barRenderer for example, provide functionality the must be specified in the chart options object.&nbsp;  To render a series as a bar graph with the bar renderer, you would first include the plugin after jqPlot:</p><blockquote><pre>&lt;script language=&quot;javascript&quot; type=&quot;text/javascript&quot; src=&quot;plugins/jqplot.barRenderer.min.js&quot;&gt;&lt;/script&gt;</pre></blockquote><p>Then you would create a chart like:</p><blockquote><pre>$.jqplot('chartdiv',  [[34.53, 56.32, 25.1, 18.6]], {series:[{renderer:$.jqplot.BarRenderer}]});</pre></blockquote><p>Here the default LineRenderer is replaced by a BarRenderer to generate a bar graph for the first (an only) series.</p></div></div></div>
